To all whom t may concern:

Be it known that I, JOHN S. McCHEsNnY, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Broom-Filler-AssemblingMachines, ,of which the following is a full, clear, concise, and eXactdescription, reference beinghad to the accompanying drawings, forming apart of this specification.

My invention relates to the manufacture of brooms and has for itsgeneral object the provision of a broom filler assembling machine whosepurpose is to permit the ready application of previously formedbands tobundles of broom straw. The machine of my invention is of particularservice in preparing bundles of broom straw with encircling bands whichare subsequently to be subject to `a collapsing operation that ispreferably eifected by a distinct mechanism but to the employment ofwhich distinct mechanism the invention is not to be limited.

In practising my invention I employ a chuck for eiecting the initialassembly of broom straw into Aa bundle and having a portion of its wall,arranged to be opened and closed, the chucky wheny closed permitting thebroom bands to be alined there-- with in position to enablethepassagetherethrough of the buttl enddof a bundle of broom straw, thechuck being `opened after the bands or rings have been. positioned aboutthe broom straw to permit of the transfer of the banded straw to anothermachine where the bands kare Lcollapsed into `permanent clampingengagement with the 40.

straw, the resulting product being a permanently assembled bundle ofstraw itself forming a broom or capable of being combined with a handleto produce ahandled broom.

In practising my present invention I employ mechanism for feeding orpermitting movement of the bands into alinement withr the chuck;mechanism for opening and closing the chuck; and actuating mechanismcommon to the aforesaid mechanisms and serving to operate the same inorderly sequence. The actuating mechanism which I prefer to employ isone that includes an operating treadle `but I do not wish to'be limitedto the source ,of ,power nor to the the mechanism illustrated inV Fig.l; Fig.

4 is a sectional view on line 4 4 of Fig. 7 g

Fig. 5 is a perspective view of a partiallyV formed product as it leavesthemachine of the invention preparatory to aband collapsing operation;Fig. 6 is'a view on line 6 6 of Fig. 7 Fig. 7 is a view on line 7 7 ofFig 6; Fig. 7 l is a detail illustrating the positions of some of theparts as they appear in Fig. 7; Fig. 8 is a view on line 8 8 of Fig. 9;and Fig. 9 is a View on line 9 9 of Fig. 8.

Like parts are indicated by similar characters Vof reference throughoutthe different figures. l

The broom straw is preferably temporarily assembled by hand inquantities just sulicient to constitute the desired brooms.

The manuallyassembled bundles of straw 5 which margin a Lgroove 6, therebeing thus V two grooves 6 which are angularly separated, the bottomring `in each vertically alined pile of rings resting upon the topsurfaces of the ledges 5 margining the groove 6 individual to such pile.The top surfaces of the rear pair of ledges 5 are in the same plane withthe bottom of the upper space or groove 2 while the top surfaces of theremaining pair of ledges 5 are in the same plane with the Vbottom of thelower space or groove 2. i

A pusher 7 is individual to each groove 2 and slides upon the ledges 5also individual to such groove. yThese pushers 7 are designed forsimultaneous operation and in their outermost positions are behind therings that rest upon'the ledges 5. As these pushers are thrust inwardlythey carry with them the lowermost rings from their places beneath theirmagazines, the pushers in their innermostpositions placing these ringsVin alinement with the bore of the chuck (now closed), the rings enteringthis position by passing throughv the grooves or openings 2 in thechuck. After a pair of rings are thus 4alined with the chuck, apreviously gathered bundle of straw, which is of sufficient amount toform the desired broom. is passed down-V wardly, butt end lirst, throughthe bore of the chuck andthe two rings which temporarily take part indefining the bore of the chuck; After the butt end of a bundle of strawVhas thus been passed through a pair of ringsthe chuck is opened, aVhalf 11 of the chuck being in hinged connection with V.the remaindenasindicated most clearly in Figs. 3,7, 7, S and 9. After thechuek has beenopened the banded bundle of straw may be removed to be subject to theopera-Vv tion of a ring collapsing machine to bring about a permanentassembly of the straw.

VIn accordance with my present invention the operation of the pushersand the opening and closing of the chuck are so ,relatively timed thatthese operations are bound to occur in predetermined and fiXed order andto this end I prefer to employ the formkof mechanism now to beVspecifically described.

f The power for" operating the machine is desirably applied by the footofthe operator tothe treadle 8 having a xed fulcrum at 9 and. connectedat an intermediate portion thereof 'with the lower end of link 10 thatis pivotally vconnected at its upper` endwith a collar 11v arranged toslide vertically upon upright guide rod 12 whose upper end carries anadjustable catch 13 that defines the extent to which the butt end ofabundle of straw lmay be inserted within the chuck 1; A spring 14,surrounding kthe guide rod `12, serves normally to position the treadleVand collar in the locations for these elements illustrated in Fig. 1.YLevers 15' (each inv, n dividual to a pusher 7) are fulcrumed at theirlower: ends and carry rollers 16 at their upper ends which are receivedbetween the ,sides of forked lugs 17 that are secured to the bottoms ofthe pushers 7 Intermediate portions of the levers 15 are connected'by,links 18 with the sleeve or collar 11 whereby the levers 15 are movedoutwardly when the treadle is depressed against the force of thespringlctoposition the pushers 7 to the rear ofand in line with thelowermost bands 3 that'are restingV upon the pairs of ledges 5 that areVindividual to the vertically alined grooves 2 and also to open thechuck. VVhen y,the treadle s released. the spring 14:, in restoring theparts to the positions illustrated in Fig. 1, forcesinward movement ofthe pushers 7 whereby two rings vare removed from the region oftheirmagazines into alinement with the bore of the chuck as illustrated mostclearly in Fig. 6, the chuck being also closed during this inwardmovement of the pushers. Y

VThe swinging section 11 of the chuck is provided with a crank arm 19 towhich motion may be imparted Athro-ugh pitman mechanism thatisoperatively connected at one end with the outer end of the crank 19and at its other end with the rear one of the two levers 15. Vhentherear pusher 7 thatl is individual tothe rear lever 15 is moved ninwardly upon the inward movement of this lever the crank 19 is turnedto close the section 11 of the chuck 1, this closure beingVK desirablyVcompleted before both bands which are being pushed by` both pushers havebeen finally positioned in alinement with the bore of the chuck. Inorder that the chuck may be closed before the two rings are valinedtherewitlnthe pitman mechanismv preferably includes'a rod 20 free tomove within the bore of a cross heador guiding sleeve 21 carried vuponthe rear lever 15 by means of a universal joint 22. The

' cross head sleeve 21 is disposed between col lars 28 that areyadjustably fixed' upon the Vrod 20, springs'2il and 25 being located bef tween the sleeve 21 andthe collars 23 as indicated most clearly inFig. 9. As the rear Vlever 15 is `moved inwardly causes the sleeve 21 topress upon the spring 25, the pressure thus exerted being transmittedthrough the forward collar 23 and the rod 20ito the, crank arm 19whereby thesection Y 11 of the chuck is ultimately closed. The closureof thechuck, however,Y is completed before the levers 15 haveAV beenmoved to their a innermost positions, continuedfinward movement of thelevers V15 beingV permitted, in order'to place the two rings inalinement with the closed chuck, byy means yofthe spring 25 that willthen yield sufficiently for this purpose. The chuck section 11 havingbeen closed before the rings arelocated within'the chuck, means maybejemployed whereby the front pusher 7 maybe brought into position tohold the. chuck closed'when the inward movements of the pushers havebeenycompleted whereby the closure ofthe chuck is so firm that thesubsequent insertion of a bundle of broom straw will not Vopen the chuckwhereby the alinement 0fA -the broom bands with the bore of the closed'chuck cannot be disturbed whilea bundle of straw is being insertedwithin the closed chuck, it being assumed that the treadle isV in itsreleased position, it being understood: that it snecessary to releasethe treadle in.VV

orderto permit theV spring 14 to move the Vpushers inwardly to closethe'ohuck. The

l action of the chuck which is effected by the pressure of the slidingcollar or cross Yhead 21 upon the spring 24, the pressure beingtransmitted from the spring 24 through a collar 23 to the rod 20. TheVchuck is Opened when the lug 28 engages the stop 29, this engagementoccurring before the pushers 7 are in their rearmost positions.Continued movement to the rear, after the complete opening of the chuck,is permitted by the spring 24 which may be further compressed after thechuck has been completely opened to permit of the further rearwardmovement of the levers 15.

It will thus be seen that I have provided mechanism whereby the openingand closing of the chuck is timed to occur in proper relation to theforward and rearward movement of the pushers and while I prefer toemploy the mechanism illustrated for Aaccomplishing this result I do notwish to be limited thereto as changes may readily be made withoutdeparting from the spirit of the invention.

`While I prefer to employ means for feeding two bands to the chuck I donot wish to be limited to the feeding of a plurality of bands to thechuck at a time, it being obvious that my invention is capable of usewhen one or more bands are to be fed into place.

Having thus described my invention I claim as new and desire to secureby Letters Patent the following 1. A broom filler assembling machineincluding a chuck for effecting the initial assembly of broom straw intobundles and having a portion of its wall arranged. to be opened andclosed; mechanism for eecting the feeding of bands into alinement withthe chuck; mechanism for opening and closing the chuck; and controllingmechanism common to the aforesaid mechanisms to effect their operationin orderly sequence, the mechanism for opening and closing the chuckincluding a crank arm connected with Copier ef thin the movable wallportion of the chuck, la, y p cross head moving with the band feeder, a

pitman rod with respect to which the cross head is movable, and springsinterposed between the cross head and portions fixed uponr the pitmanrod, one spring serving to permit closure of the chuck before the bandsare fed into position and the other spring permitting opening of thechuck before the band feeder has been completely withdrawn.

2. A broom filler assembling machine including a chuck for eecting theinitial assembly of broom straw into bundles and having a portion of itswall arranged'to be opened and closed; mechanism for effecting thefeeding of bands into alinement with the chuck; mechanism for openingand closing the chuck; andcontrolling mechanism common to the aforesaidmechanisms to effect their operation in orderly sequence, the mechanismfor opening and closing the chuck including a crank arm connected withthe movable wall portion of the chuck, a cross head moving with the bandfeeder, a pitman rod with respect to which the cross head is movable,and springs interposed between the cross head and portions fixed uponthe pitman rod, one spring serving to permit closure of the chuck beforethe bands are fed into position and the other spring permitting openingof the chuck before the band feeder has been completely withdrawn, thefeeder carrying a portion which is brought into position to maintain thechuck closed when the bands are fed into place.
